Specificity

This assay has high sensitivity and excellent specificity for detection of Antidiuretic Hormone (ADH).
No significant cross-reactivity or interference between Antidiuretic Hormone (ADH) and analogues was observed.

Recovery

Matrices listed below were spiked with certain level of recombinant Antidiuretic Hormone (ADH) and the recovery rates were calculated by comparing the measured value to the expected amount of Antidiuretic Hormone (ADH) in samples.

Matrix     Recovery range (%)     Average(%)    

serum(n=5)     88-97     94    

EDTA plasma(n=5)     80-90     86    

heparin plasma(n=5)     91-101     96    

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Antidiuretic Hormone (ADH) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Antidiuretic Hormone (ADH) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

抗利尿激素(ADH)检测试剂盒Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Antidiuretic Hormone (ADH) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample     1:2     1:4     1:8     1:16    

serum(n=5)     78-101%     94-103%     78-90%     86-93%    

EDTA plasma(n=5)     83-91%     79-101%     79-93%     82-92%    

heparin plasma(n=5)     78-90%     95-102%     90-97%     93-105%    

Stability

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

抗利尿激素(ADH)检测试剂盒Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Antidiuretic Hormone (ADH) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Antidiuretic Hormone (ADH) and unlabeled Antidiuretic Hormone (ADH) (Standards or samples) with the pre-coated antibody specific to Antidiuretic Hormone (ADH). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Antidiuretic Hormone (ADH) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Antidiuretic Hormone (ADH) in the sample.
